Abstract
BACKGROUND: Clinicians and medical researchers increasingly turn to nonformal online platforms to promote research. Altmetric Attention Score (AAS) is a quantitative measurement of online influence of research in real time. The objective of this study is to determine if AAS correlates with traditional bibliometrics in the orthopaedic literature. MATERIALS AND METHODS: From the 15 orthopaedic journals with the highest impact factor, the 10 most cited articles from each journal were reviewed for 2014 -2017. For each article, AAS was collected using the Altmetric Bookmarklet application and citation count from SCOPUS. Journal impact factor was recorded using Journal Citation Reports. Statistical analysis included Pearson's and Spearman's correlation coefficients. RESULTS: A total of 600 articles were analyzed. A significant positive correlation was found between citation count and AAS for 2014 (r = 0.3188, p < 0.0001), and no correlation for 2015 (r = 0.1504, P = 0.0653), 2016 (r = 0.0087, P = 0.9157), and 2017 (r = 0.0061, P = 0.9408). There was no significant correlation between impact factor and AAS in 2014 (r = 0.4312, P = 0.1085), 2015 (r = 0.3850, P = 0.1565), 2016 (r = 0.1460, P = 0.6035) and 2017 (r = 0.0451 P = 0.8732). CONCLUSIONS: AAS and traditional bibliometrics are currently not strongly correlated in orthopaedic literature. Citations take years to accumulate and AAS represents immediate influence of an article. An amalgamation of traditional bibliometrics and AAS may prove useful in determining the short- and long-term impact and influence of publications in orthopaedics.
